No thanks, I'll skip the free cheat sheetsThis free API testing scenario lab collects the exact scenarios companies put in front of SDETs — each with its test conditions, expected result, and a ready-to-adapt RestAssured assertion. Filter by domain or test type and use them as a checklist for your own API suite.
Strong API testers do not test endpoints — they test scenarios: happy path, boundary, auth failure, schema drift, and negative input. Each card here frames a real scenario (the endpoint, the purpose, the input condition, the expected result) so you practise choosing what to assert, which is exactly what interviewers probe.
Every scenario ships with a RestAssured assertion you can lift straight into a test — status code, JSON body path, schema validation or header checks. Copy it, swap in your base URI and payload, and you have a starting test. Over 25 scenarios that is a compact regression skeleton for any REST service.
Yes, it runs entirely in your browser and is free to use.
The domain, endpoint, test purpose, a test-case ID, the input condition, the expected result, and a ready RestAssured assertion.
Yes — they are written in RestAssured’s standard given/when/then style, so you copy the assertion and adapt the base URI and payload.
Yes, the scenarios reflect the kind of practical API cases SDETs are asked to design tests for, including negative and security cases.
